2017年，在KEK电子正电子直线加速器中安装了64个脉冲磁体（28个四极和36个超导磁体），用于同时注入四个不同的环。由于每个环需要不同的注入能量，因此注入器直线加速器中的磁场必须根据束的目的地逐次改变（每20 ms）。为了实现这种操作，新型的脉冲电源和一个事件的定时系统兼容的基于PXI的控制系统的开发。该系统安装调试成功，运行一年来未出现严重故障。
In 2017, sixty-four pulsed magnets (28 quadrupoles and 36 steerings) were installed in the KEK electron positron linac for simultaneous injection to four different rings. Since each ring requires different injection energy, magnetic field in the injector linac has to be changed shot by shot (every 20 ms) according to the destination of the beam. To realize such operation, novel pulsed power supplies and an EVENT timing system compatible PXI based control system were developed. Installation and commissioning of the system were successful and it has been working for one year without severe trouble.
